5 Series E60 M5 (S85) SAL
To rock the vehicle free, shift gear rapidly from 1st gear, via position "N" to position "R" and vice versa. Perform
the gearshift within approximately 0.8 seconds, as otherwise the gear lever lock (shift-lock) will be activated.
Protection of valves
All valves in the transmission are activated periodically to protect the valves from becoming soiled. In this
process, the valves are supplied with current so that they are moved and cleaned, but the shift cylinder is not
moved.
Switch-on conditions:
•
During wake-up of the SMG control unit
•
Cyclically after expiry of a specified time
Self-diagnosis during a pressure loss
Defects (e.g. leakage) are detected because the hydraulic pump switches on more frequently than is normal.
The SMG control unit limits the switch-on time.
If there is a fault, the Check-Control symbol in the LCD display of the instrument cluster lights up.
When the hydraulic pump is running, the pressure increase is monitored in response to the switch-on time. The
gear is deselected if there is a defect in the hydraulic pump or a pressure value is undercut (e.g. sudden
pressure loss). The hydraulic control unit is deselected.
Emergency program
In the emergency program, the vehicle remains operational, albeit with limitations.
Depending on the type of transmission fault, the vehicle may no longer be operational after a vehicle standstill.
Operation
Activate launch control
(Note preconditions for activating launch control!)
The gear lever must be pushed forwards and the accelerator pedal must be pressed fully down. The engine is
regulated to the optimum starting speed.
When the gear lever is released, the vehicle is accelerated with an ideally regulated slip for as long as the
accelerator pedal is still pressed down.
The sequential M transmission with "Drivelogic" automatically changes gear from 1st to 7th until the top speed
has been reached. Gearshifts are made shortly before the maximum engine number for the gear concerned is
reached.
Deactivate launch control
•
By the position of the accelerator pedal (releasing the kickdown position)
or
•
By a manual gearshift
or
•
By activating DSC
After a launch control operation, the vehicle must be driven over a certain distance before the next launch
control operation is enabled.
